I am trying to install pillow using 'pip'

Question

I'm trying to install Pillow library and it fails in the setup. After the download completed I get a long list of errors.

 Complete output (174 lines):

The headers or library files could not be found for zlib, a required dependency when compiling Pillow from source.

Answer 1

getting a latest update of python is not always too good, especially for the module
There are some module that does not support latest python

However , there is pip3
May you try pip3 install pillow

I'm Currently
python 3.7.9

Answer 2

Python 3.9 is not even released for 10 days yet. As far as i see a lot of the packages are not supporting Python 3.9 yet. I think your best bet is to uninstall Python 3.9 and install Python 3.8.6. If you want you could try to download the pillow wheels from here and try to install it may it will work.

The following command might also help.

pip intstall pipwin
pipwin install <package name>
